Something new, something old (Part 2)

THIS is the second part of the three-part series in the Two Knights Defense. After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Na5 6.Bb5+ c6 7.dxc6 bxc6 8.Be2 h6, White may continue with 9.Nf3 or 9.Nh3. The former move is examined in this post.

The knight-retreat to f3 – the modern approach

9.Nf3!?

Diagram 2 - Position after 9.Nf3.

The usual move here is 9.Nf3, after which Black obtains some initiative after 9... e4 10.Ne5 Bd6 (this is considered to be the main line of the Two Knights Defense). This is the favorite move of Alexander Morozevich who scored notable wins with it against Alexander Onischuk (twice) and Yuri Balashov. English number one, Nigel Short, a former world championship challenger, had employed this move successfully, although he was more successful with the Steinitz variation.

This is also the move of choice by the 13th world championship, Garry Kasparov (1985-2000), in a rapid game against another former world championship challenger, Dutch GM Jan Timman.

9… e4 10.Ne5 Bd6 11.Nc4?

This knight move—already the fifth just within the first 11 moves—is a blatant mistake, most likely a losing one, because after the normal exchange of pieces White finds himself greatly lagging behind in development. When a player uses 5 moves with a piece (his knight) just to have it exchanged to his opponent’s knight on the rim, there must be something wrong somewhere—evidently a faulty strategy.

The correct move was 11.d4. The position after 11… exd3 12.Nxd3 has brought about victories to Morozevich, Short, and Kasparov among a host of prominent players.

11… Nxc4 12.Bxc4 0–0 13.0–0??

White's last move was completely mistaken—a lucid example of castling without thinking. The position demands that development matters more over “king safety." At the expense of a pawn Black has a big lead in development and has two ways of continuing from here.
